The national road DN7 has two ramifications in Arad County. The first one is DN7B, which connects the national road to Turnu, where there is another border crossing with Hungary, whereas DN7G serves as the link between the road at Nădlac and the A1 motorway near the Nădlac II–Csanádpalota border crossing.
Most of the traffic formerly carried by the national road between Bucharest – Pitești and Sibiu – Nădlac now takes the A1 motorway, which will also carry most traffic between Pitești and Sibiu upon its completion.
